Usage

  let { calcGasRadius } = require("sp-gas")
  let speed = 0 // 泄漏风速
  let radius = 0 // 泄漏开口半径
  let p1 = 3.17 //临界压力
  let p2 = 1393 //两相混合物的平均密度
  let cp = 0.957 //两相混合物比定压热容
  let t = 24.85 //两相混合物温度
  let t0 = -34.15 //液体沸点温度
  let h = 280 //液体汽化热
  let c0 = 890 // 死亡浓度
  let c1 = 300 // 重伤浓度
  let c2 = 90 // 轻伤浓度
  let c3 = 9 // 反应浓度
  let r0 = calcGasRadius(speed, c0, radius,p1, p2, cp, t, t0, h) // 致死半径
  let r1 = calcGasRadius(speed, c1, radius,p1, p2, cp, t, t0, h) // 重伤半径
  let r2 = calcGasRadius(speed, c2, radius,p1, p2, cp, t, t0, h) // 轻伤半径
  let r3 = calcGasRadius(speed, c3, radius,p1, p2, cp, t, t0, h) // 警戒半径
